Short description
Bestämningsnycklar | Morfologi | Morfometri
Occurs usually in shallow sandy runs and pools of creeks and small to large rivers (Ref. 86798). Oviparous, probably open substratum spawners like congeners (Ref. 205).
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver
The pelagic-broadcast spawning behavior consisted of males pursuing a single female and nudging her abdominal region. When the female was ready to spawn, a single male wrapped around the female at which time eggs and milt were simultaneously expelled. Reproduction usually consisted of several individual spawning episodes with at least 10-min intervals between events (Ref. 35784).
